<div class="textblock"><p >High level APIs including combined quotient and remainder functions for 32 and 64 bit accelerated by the hardware divider. </p>
<p >These functions all call __aeabi_idiv0 or __aebi_ldiv0 on division by zero passing the largest applicably signed value</p>
<p >Functions with unsafe in their name do not save/restore divider state, so are unsafe to call from interrupts. Unsafe functions are slightly faster. </p>
